For any purchasers, open it up, remove heat-sink, clean both CPU & heatsink and put some good paste like AS5 or better and you will see far better temps and thus much more consistent Turbo. Don't know what "paste" Dell uses but they cheapened out.

My own 9333 with 4650U used to hit over 90C all the time, now it barely hits 80C! Or push long-term Turbo to 20W (or 25 ;) and then it may hit 90C.

(Done the same to Lenovo Carbon X1 and that worked fantastic too!)

If you buy the 9350 then sell the cheap PM951 and buy either an SM951 or Pro 950 and then let it fly.

hey Adrian, I own the dell xps 13 9350 16GB internal memory/ram, 512GB SSD, i7-6560U intel iris 540 (fully-loaded version, I paid $1500 for this laptop)

what is this "cheap PM951" your talking about replacing? I'm interested in upgrading the xps 13 in anyway possible to make it run better and more efficiently, I need to take it in somewhere to have the pasting done, cause I have no idea on how to do so myself, but I am good with my hands, but I don't know if I want to try it myself until I see it done at-least. but anyway, I was wondering what you meant by "if you buy the dell xps13, get rid of the cheap pm951 and get pro 950". is this a component inside the laptop I can buy and replace to make it run better? please explain, email me if possible! thanks Adrian for your time!

Was content adaptive brightness control (CABC/DBC) disabled before performing the calibration on the display panel? There is no mention of this at all in the article, if it was not disabled using the software provided by Dell then the ICC file provided is completely inaccurate.

hi,

May i know how long is the battery life for the FHD non-touch xps 13 with intel iris 540 graphics card in terms of  web browsing and watching movies. Would it be in the same range as the 520 graphic card or will there be a vast difference.

thanks in advance, :)

I'd like to know if the throttling is due to thermal or TDP limits.

While stressing both the CPU and GPU it will TDP throttle despite having thermal headroom (~20ºC to thermal limit). On top of that, unlike the i7-6500U which can TDP up to 25W the i7-6560U is locked at 15W. I've seen it turbo up to ~25W but it was only for about a second before forcing the CPU speed way down in order to allow more power to the GPU. Locking the TDP at 15W on this CPU makes no sense and I have no idea why Intel did so. If the system can provide the extra power (the XPS 13 can since all other models can TDP up to 25W) why would you not use to to full the thermal headroom and allow the CPU and GPU to run at their full potential. I would love to get an answer from Intel as to why they have artificially crippled this chip.

Notice no TDP up option, only down:

Notice the TDP up option to 25W:
http://ark.intel.com/products/88194/Intel-Core-i7-6500U-Processor-4M-Cache-up-to-3_10-GHz

I am also wondering if the BIOS update improved the battery life, as it was with  the i7-6500U version (see update in the respective test).

thanks for review,

we are waiting HP ZBook 17 G3 with "17.3 inch LED FHD UWVA Anti-Glare flat (1920x1080) "

to see if it's could get the first place in Best Notebook Display in your website  8).

Hi there,

is it possible to know which Bios has been used? Is this the latest one or the latest would bring additional battery life (since this test uses the 256/512)?

Thanks for the coil whine heads up. This is an absolute deal breaker, for me at least. On top of that, taking into account all the cons mentioned, I am amazed the machine scored 87%...

The previous model (9343) also had coil whine, but it was barely audible unless you were in a completely silent room or put you ear to the laptop. I assume it is the same here.

I'd like to know if the throttling is due to thermal or TDP limits.

I am wondering if the thunderbolt3 controller uses PCIe 3.0 x2 (20Gbps) or PCIe 3.0 x4 (40Gbps).
I noticed that on XPS 15 9550, when I looked at the PCIe configuration with HWINFO64, its TB3 seems to have only x2 PCIe 3.0. And I am thinking if similar thing happens on XPS 13.

I think it's worth mentioning that the 512GB SSD is in parts much faster than the 256GB version. The way Dell designs its models you have to take the i7 if you want the bigger SSD (and 16GB RAM). This review came out just in time as I found it difficult to get any benchmarks of the 512GB SSD used here.
The new i7 seems to disappoint though, especially if compared to the also very compact Surface Pro 4. I still consider the i5, 8GB, 256GB, QHD and an SSD upgrade in 2 years to a Brazilian Byte.

What I don't understand is that you don't have the i5 version of the XPS13 (with 8GB, 256GB) in your comparison tables.

Oh, you've linked the wrong XPS13 in your price comparison.

I'm a bit confused right now as well. Have been waiting for this test quite a while for an XPS with an IRIS GPU sounded really great. Now this model seems to be..."worse?" than the non-iris-models? (Bad keyboard? bad sound? those were not mentioned in the other models revue, were they?)

I'd actually like a short comparison on non-iris vs iris-versions of the xps 13 and ideally a bit more information on the IRIS itself (for there are only two 540 devices yet tested)  :-\

wow. this model took quite a 'beating' in this review and still scored 87% Is it maybe because of low the price tag of only 1300 USD  :p

Please correct the price because the model in question costs 2000 USD (dell.us) or 1900 Euro (dell.de)
